Pfizer wishes to make all aware of the consolidation of the Pfizer Patient Assistance into one program call Pfizer RX Pathways.

PfizerRXPathways2014highlights their efforts to simplify and streamline patient assistant offerings.

Pfizer stresses that they remain committed to helping patients in need get access to our medicines, and sincerely hope that the consolidation of patient assistance offerings will make it even easier for eligible patients to apply and enroll.

The annual GIST and Sarcoma Cancer Research Conference, organized by the GIST Cancer Research Fund, serves as an invaluable forum for patients and their families to hear about the latest advances in the field from scientists and clinicians at Brigham and Women’s Hospital (BWH) and Dana-Farber Cancer Institute (DFCI).

Last year’s event, which was held in April, was no exception. More than a dozen investigators, physicians, and caregivers at the leading edge of research and care from both BWH and DFCI gathered at the conference to share the latest findings, clinical trial updates, and therapeutic advances with patients, which provide them with the knowledge they need to make informed decisions about their own treatment strategies. Below is a brief synopsis of just a few of the many research highlights from the day’s presentations.

Memorial Sloan-Kettering Cancer Center (MSKCC) is preparing for what it calls “a breakthrough clinical trial” that will test a new drug that uses a MEK inhibitor to target ETV1 in combination with imatinib on a small group of newly diagnosed GIST patients with advanced disease.

We hope to begin recruitment in August, said Dr. William Tap, Section Chief of Sarcoma Oncology at MSKCC. The Phase II trial will be small, with only about 45 participants, and will only have

one site at MSKCC in New York City, he said. That’s because “we just want to show that this approach works,” before recruiting for a larger scale trial, Dr. Tap said. There will be a Phase I portion of the trial to define the Phase II doses of the combination regimen.

The trial is unique because most new GIST clinical trials recruit patients that already have taken imatinib, sunitinib or other drugs and have already developed resistance to those drugs. This trial will try to show that treatment with a combination of imatinib and the MEK inhibitor from the start will be even more effective in combating GIST and will reduce the likelihood of secondary mutations that cause resistance.

Novartis Pharmaceuticals is co-developing the MEK inhibitor, MEK162, with Array Biopharma. MEK162 has been through Phase I trials and recently completed a Phase II trial in NRAS-mutant melanoma.

Dr. Tap said the research that opened the way to this new approach was led by his colleague at MSKCC, Dr. Ping Chi. She was able to show that ETV1, a transcription factor, was essential to the survival of GIST; while it was hard to target ETV1 because it didn’t have molecule-binding pockets that could be blocked by drugs, she found a way around this problem by discovering that MEK inhibitors could do that job.

“MEK inhibitors alone doesn’t seem to be great, but by doing combination therapy with imatinib we get a dramatic response,” Dr. Chi said. ETV1 is a master regulator that is highly expressed in all GISTS.

“Ping’s discovery is one of the major discoveries that we have seen in GIST research since the discovery of KIT,” Dr. Tap said.
